GENERAL DESCRIPTION
The ADM1062 Super Sequencer? is a configurable supervisory/
sequencing device that offers a single-chip solution for supply
monitoring and sequencing in multiple-supply systems. In addition
to these functions, the ADM1062 integrates a 12-bit ADC and six
8-bit voltage output DACs. These circuits can be used to implement
a closed-loop margining system that enables supply adjustment
by altering either the feedback node or the reference of a dc-to-dc
converter using the DAC outputs.
